### MP-320 Invalid function selected

The MP cannot process the requested function in stand-alone operation. You may have entered a function that cannot be used in the stand-alone operation.

This error only occurs when the MP front panel on an MP-30/35 system is used.

What you should do:

1. To clear the error, press the MP CLEAR key on the MP front panel.

2. Enter a valid command. The mistake may be caused by operator input.
